210 POLYPODIUM, § EUPOLYPODIUM. 



furaceous above with appressed scales, copiously so beneath 

 where they are persistent whitish or pale tawny colour squar- 

 rose ovato-acuminate hair-pointed toothed or beautifully ci- 

 liated dark-brown in the disk, pinnfe and segments generally 

 few 11-15 (rarely 30) distant especially the inferior ones 

 1-24 inches long oblong or subspathulato-oblong obtuse the 

 very base broad-adnate and decurrent especially at the in- 

 ferior base (venation of Marginaria, Mettenius, Fee), sori 

 frequent dark-brown arranged between the costule and mar- 

 gin very much concealed by the scales. — Lirm. Sp. PI. p.

 of Fee), Linden, n. 515. Chacapoyas, Peru, Mathews, n. 3281. Andes of 

 Ecuador, Spruce, n. 5235, Jameson, n. 3482 (one specimen passing into P. tri- 

 dens). — The ordinary form, with few segments and sul)spathulate segments, is a 

 very distinct-looking plant, and the scales are copious andvery squarrose beneath. 

 In the so-called P. thysanolepis they are not close-placed, and are very per- 

 manent ; such specimens look like overgrown forms of P. incaymm, and they cer- 

 tainly are not more unlike that species than the type of the species, Plumier's 

 figure, is to our present plant, if it l)e not awfully exaggerated in the plate 79, 

 where the frond is given as 2 feet 5 inches long (without the stipes), with 77 

 pinnae 3 inclies long and nearly half an inch wide ! Yet in other respects the 

 figure is satisfactory.

 deeply forked or tripartite segments. My very fine specimens in that condition 

 are from Mr. Cuming and Capt. Wood, but accompanied by others of the same
